I have a 1994 JGC with the same engine. It has nearly 300,000 miles on the original engine. My oil pressure gauge goes from 0 - 80 at any given time with no apparent reason. Instead of relying on the gauge I rely on the performance of the engine. Oil and filter changes every 3500 miles and everything has been fine since I bought my Jeep 15 years ago. My mechanic tells me its as strong now as its ever been.

9/11/11 is a good day to commit to a jihad on our crappy trucks that we repair and repair and repair. I would like to listen to my gps calmly saying "recalculating" as it plunges to its death at a local cliff. I will never buy an american car again. Sad. :+( BTW, if your Jeep product is red, you can call it a "crimson jihad".
No I am not trying to make fun of the sad events at 9/11, but only to poke fun at a vehicle that J have poured thousands of dollars into.

I am not car savvy at all. My Jeep is an automatic... I've been having some problems- staling when I back up, some slack in shifting, and possibly misfiring of the spark plugs. I took it in for a mechanic (friend of a friend) to do an electrical check of some kind (free). He said about 4 spark plugs were misfiring. He told me he could run a check on the whole engine ($75) but the spark plugs probably needed to be changed. Trying to save a little money, I bought the spark plugs and my ex and oldest son offered to do it for me. They had no clue what they were doing either. So, they removed all the wires on one side at once before they realized they were supposed to do it one at a time. They said all the wires on that side seemed to be in the wrong place (according to the diagram). They replaced all the plugs and it wouldn't crank. Then they put new wires and a new distributor cap cord on. It still won't crank. I'm concerned that it's something more serious. But, before they worked on it, it would crank. Could there be an alternative firing order for the cords to the spark plugs? That's what we keep wondering, because they said the old cords were in a different order when it was running. We really need help! I can't afford to take it in!

You have got to take it in. The reason your plugs are not firing is due to an ignition or computer issue. 4 plugs do not go bad all at once. The plugs are a symptom of a greater electrical issue.

deeceesd. Thanks for the posts. I'm having the same issue as you described on my '11 GC 5.7L. I have not taken it to the dealer yet. I'm at approximately 3,000 miles. Curious of the fix if you ever got a resolution from Chrysler? I too was questioning the locking torque converter.

I am sorry your Grand Cherokee is deceased. Are there funeral Arrangements? Possibly a viewing? Or is it so horribly messed up that it is a closed repair bay service? LOL.
I still love my Grand Cherokee, especially the music of the V8. however, never a day goes by that I do not regret buying it and sinking 10,000.00 in repairs over the past 5 years. It has been difficult. Every repair I have had is over $2000.00.
I will not buy one again. It was just too much. I am gun-shy of Chrysler forever!

Well first things first...you want to start with the most basic, most importantly, cheapest things first. (I just realized how old this post is...lol...still) If the fuel pump goes out it won't crank at all...you can turn the key to the ON position just before trying to start it. You should hear the fuel pump kick on for just a sec or two at the rear of the vehicle (it is at the top of the gas tank). In the fuel system I would start with the fuel filter first. People would be amazed to know the types of problems which can be caused by not keeping up with regular maintenance of a vehicle (changing the oil and oil filter, changing the fuel filter, changing the spark plugs and spark plug wires, chainging the air filter.) I had a 1994 Jeep Grand Cherokee with the inline 6 cylinder engine. Very simple cars to work on. Its system does not have things such as a throttle adjustment screw...if it is not idling or running correctly start with these minor things first (according to the symptoms of the issue you are having...starting system, etc...). You have to drop the gas tank to get to the fuel pump on these vehicles...its not that difficult but a new one does cost about $300. Had to do this on mine while I owned it. These tips can be used with almost all vehicles...they are all very similar. Except for CHRYSLER!!!! Steer clear of those!!!! lol. My wife owns a 97 Sebring and it has given me and all mechanics I know more problems than any vehicle.

my 1996 gc laredo w 218.000 miles has been dying while driving or coming to a stop. The oil pressure dropped to zero just before. No "check engine light". I could restart it immediately dropping into neutral while coasting along. this worked good on freeways but it's stressful to say the least. Have had my mechanic replace coolant sensor, temp sensor, crank position sensor & new battery & belt. Display kept showing "bad coolant sensor. Then it wouldn't start. Finally took it to jeep dealer who replaced plugs & wires, cleaned distributor, new gasket on valve cover for $700. Said they wouldn't reset the computer module. After driving it for 4 hours and about 300 miles running just great it up and dies again, once when stopping, then when underway. Jeep dealer says it needs a new PCM & ignition coil for another $1000. Hate give up this car as it goes anywhere and is a joy to drive, but is it worth it now? Anyone with any more ideas?

I just went through this with my 94 JGC. I did all the same things you did. It did end up being the PCM. Once the PCM was replaced for $500 I have had no issues. When you think about it, it makes sense. It is a very old computer, how long is it supposed to last. Mine was in bad shape when they pulled it off. It also corrected my hard starting problem. Good luck.

Hi...did you ever get a fix for your misfire issue? I have been returning mine for updates and checks for this for 10 months. Finally pulled spark plugs myself and found two cylinders appearing to burning very lean and a couple others looking rich and some indications of oil going through them. Finally got call from Customer service and was told no codes so no problem!!!!! Informed her that issue showed up after about 3,000 and was minor annoyance but has continually gotten worse. they did not care..no codes, no problem was the set "line". Email me if possible and let me know? daboothselectca.com
